Drill-driven compressor head

ABSTRACT

A portable drill-driven compressor head. A compressor assembly is configured with a drill attachment which harnesses the rotation of a main shaft to pressurize air and deliver such pressurized air through a hose.

BACKGROUND AND SUMMARY

One key element to vehicle safety and performance is the maintenance ofproper tire air pressure. To facilitate the maintenance of tire airpressure, consumer air pumps exist in various forms including portablepumps that may powered by a vehicle's auxiliary power outlet. Theseconventional approaches, however, have limited utility particularly inconsideration of larger vehicles and trailers which may both at timesrequire inflation of tires positioned beyond the length of the portablepump's hose.

The inadequacy of conventional portable air pumps is particularly feltby individuals in industries that require considerable travel ormovement of materials that necessitates a trailer or other method ofexpanding the typical carrying capacity of the individual's vehicle. Incertain of these industries, such as those relating to constructionservices, it is not uncommon for the individual to be carrying withinthe vehicle (or otherwise have access to) a portable drill.

The present disclosure describes a drill-driven compressor head thateffectively provides an improved portable air pump utilizing a portabledrill as a driving mechanism for the delivery of pressurized air into avehicle tire. Such an improved portable air pump is not only easy to usebut also accommodates circumstances or scenarios conventional pumps areill-equipped to address.

DETAILED DESCRIPTION

This description, with references to the figures, presents non-limitingexamples of embodiments of the present disclosure.

As depicted in FIG. 1 , in certain embodiments of the presentdisclosure, drill-driven compressor head includes a compressionassembly/pump 110 and a compression actuator/drive shaft 116. A housingelement/pump housing 111 may be incorporated into said drill-drivencompressor head to substantially contain compression assembly/pump 110.Additionally, housing element/pump housing 111 may be configured with anaperture to receive compression actuator/drive shaft 116 such thatcompression actuator/drive shaft 116 may engage with compressionassembly/pump 110.

In these embodiments, compression actuator/drive shaft 116 may be ashaft configured to connect to a portable automatic drill such as aconventional hand drill. To this end, compression actuator/drive shaft116 may be configured with a quick connect apex bit, chucking drillhead, or other conventional means for allowing a shaft to engage with adrill.

In some embodiments, compression assembly/pump 110 may utilize amechanical piston to produce and deliver pressurized air. Such acompression assembly/pump 110 may include an assembly housing/pumphousing 111, a connecting housing/pump housing 111, rotating member 115,and a ring element/piston 113. Ring element/piston 113 may be coupled toconnecting rod/pump actuator 112 which is also coupled to rotatingmember 115. Rotating member 115 may be a crankshaft including aflywheel. Rotating member 115 may be configured to receive one end ofcompression actuator/drive shaft 116 thereby allowing for rotation ofrotating member 115 and actuation of the piston mechanism when rotatingmember 115 is coupled to compression actuator/drive shaft 116, whichitself may be coupled to a drill.

Assembly housing/pump housing 111 may define an interior volume 114wherein ring element/piston 113 may be disposed. Assembly housing/pumphousing 111 may be configured with an airflow element/valve member 120that partially defines interior volume 114 and allows air to flow intoor out of interior volume 114 when ring element/piston 113 is beingactuated. In some embodiments, airflow element/valve member 120 may be areed valve.

Although these embodiments have been described as using a mechanicalpiston, those of ordinary skill in the art would understand that othercompressor structures (such as a rotary screw compressor) may also beused.

Compression assembly/pump 110 may also include a compressioncap/cylinder head 130. Compression cap/cylinder head 130 may beconfigured to couple with assembly housing/pump housing 111 to define achamber/interior volume 114. Compression cap/cylinder head 130 may beconfigured with an intake aperture/valve member 120 and an outletaperture 133. Intake aperture/valve member 120 may be configured toallow air to flow through compression cap/cylinder head 130 intointerior volume 114. Outlet aperture 133 may be configured to receive ahose 220 through which pressurized air created by the piston mechanismand contained within chamber/interior volume 114 may be delivered.Compression cap/cylinder head 130 may be further configured to couplewith a pressure gauge 210.

In various embodiments, housing element/pump housing 111 may be used tosecure the various compression assembly components to one another. Asshown in FIGS. 1-3 , housing element/pump housing 111 may be configuredwith at least one opening to receive a screw. Compression cap/cylinderhead 130 may be similarly configured such that a screw may pass throughcompression cap/cylinder head 130 and into housing element/pump housing111 to secure compression cap/cylinder head 130 to assembly housing/pumphousing 111. Housing element/pump housing 111 may also be configuredwith a front-facing surface that is configured to receive compressionactuator/drive shaft 116. One or more bearings may be used withinhousing element/pump housing 111 to facilitate the operable connectionof compression actuator/drive shaft 116 and compression assembly/pump110.

Although the disclosure has been explained in relation to variousembodiments thereof, it is to be understood that many other possiblemodifications and variations can be made without departing from thespirit and scope of the disclosure.
